Specification of Letters Patent.

Patented Dec. 3,1912.

Original application filed December 30, 1911, Serial No. 668,632.Divided and this application liledf'llrch To all whom it may concern:

Be it known that I, ToNJEs AUGUST CARL BOTH, a citizen of the UnitedStates, and a resident of Malden, in the county of Middlesex and Stateof Massachusetts, have invented certain new and useful Improvements inMechanical Movements and Electric-Light Sockets,- of which the followingis a specification, taken in connection with the accompanying drawing,which forms a part of the same, this application being a division lofvmy copendiug' application, Serin No. 668,632.

My invention relates to mechanical movements adapted for' universalapplication. Further to: electric light sockets and to certain detailsof construction of both the mechanical movement and the electric lightsocket, which will be more fully hereinafter described in thespecification and pointed out in the claims.

I have shown my mechanical movement as afswitch mechanism in an electriclightsocket, to which it is particularly adapted owing to itssimplicity, theI few parts, and the small space occupied by them. lVhenso used it makes a quick make and a quick break of the electric current,Without arcing, upon the operation of the driving member in eitherdirection.

Among' other advantages my mechanical movement permitsthe socket to beformed4 a switch mechanism in anelectric light' socket, but it is vto beunderstood, ofcourse, that the mechanical movement is not to be limitedto this use.

In the accompanying drawing showing illustrative embodiments of myinvention and in which thev same reference numerals refer to similarparts in the several iigures,-Figure l is alongitudinal vertical sectionthrough my electric light socket, one of the insulating members beingshown in side elevation; Fig. 2 isav longitudinal vertical scctionthrough my electric light socket, substantially at right angles to thesection shown in Fig. 1: Fig. 3 is a side elevation of the screw shell;Fig. 4 is a plan view of the screw, shell 21 is Serial No. 687,183.

screw shell; Fig. 5 -is a perspective .View of vone form of resilientdriven member, the parts being shown disconnected; Fig. 6 is aperspective view of the preferred form of driving member; Fig. 7 is aplan View of a blank from which one form of driven member may be formed;Fig. 8 is a side elevation of the driven member formed by bending theblank illustrated in Fig. o horizontal section substantially on the line9-9 of Fig. 2; Fig. 10 is a fragmentary sectional view showing a detail.i

In the illustrative embodiments of my invention shown in the drawing, 1is an electric light socket formed of two complementar)v insulatingmembers 2 and 3 having meeting surfaces 4, l, Fig.

the electric lightsocket, though portionsl of the meeting surfaces arepreferably offset as at 5, Fig. 2. These insulating members 2 and 3 arepreferably formed from porcelain and without cross holes and each ofthem is l 2, which coincide. substantially with the longitudinal axisof.

7; Fig. 9 is 'a provided with a recess (3 which togetherf" form aninterior recess er chamber T for,y the reception of my mechanicalmovement 1 when it is used as a switch mechanism in this form ofelectric light socket. Each of the recesses (3, 6 has an offset ordeeper recess S', F ig. 2, which form guides :for the otl'setportionst), 9, Fig. 5, or 10, 10, Fig. 7, of the respective resilient drivenmembers 11 and l2. I also form in theroii'perating faces of each of theinsulating members 2 andB, two demi-circular openings 13, 1l to receivethe respective cams 15 and 1G carried by the driving member 17. Theholes or recesses 1S. 18, Fig. 2 are also molded in the insulatingmembers 2 and 3 for the reception Cf the bearings 19, 19 of theintermediate er movable hill and valley member 20. l attach theinsulating membersQl and P to a lamp holding member which is usually,though not necessarily, in the form of a screw shell 21. The upperportion of the provided with a lip 22,' Figs. 1, 3 and 4 which extendsup into the interior chamber i' and forms one contact. l also prefe ablyprovide the head of this screw shell Q1 with a dovetail 23 to ccperatewith the dnvetails 24, 2-1 formed in-the relspective insulating membersQ and I also preferably provide each cf the insulating members 2 and 3with another doretail 25, Fig. 1, which takes under the head 26 of thescrew shell 21. In this form of' my invention the intermediate ormovable hill and valley member is formed of some insulating materialandprovided at each end with' :i 'valley 28,-each yalley having a ledgeor shoulder 29 and' a boot, kicker or accelcrater 30. The hill l 31 isthat portion of Fig. 5. hierin these engaging surfaces and Sllas hook onone member and a slot 2o" the other', the particular forml of engagingsurfacesv shown, however, are merely by 'ivay of example. The stamping131 which fl. will refer,1 to as e' shoe, is preferably,

' `instead .of using a resilient member Yform-ed of .n plurality etparts, I may in seine cases use a resilient member termedl though notAnecessarily provided with the Aoffsets 9, '9.' rlhe upper stamping 32 ispro! videdvwith an engaging surface 35 to'eooperate with the Amovableintermediate or hill. and valley member20. On assembling the 'shoe 131and the member 32,v a very strong resilient member 11 lis termed.

. out ot one piece of material. l have shown such a. resilient member inFigs.

l and 8.

- ln this toi-m, the blank 36, Fig. 7, is preti' which would lie et' the`#anni erablyprovided wftli the otsets 10, 10- and Aalso with one ormore ribs 37 37 which serve to strengthen the resilient member 12 whenthe blanli is bent backv on itself, Fig. 8. In this form, the surface 38cooperates with the intermediate hill and valley member 20.

.l have. fou'iid that it is quite desirable to insulate the hey ordriving member 17 from the switch mechanism so' that a metal key or akey iorined et other conducting mitte.-l

rial 40 may bev placed upon the end 3l) ot the y driving member,

lt is often quite desirableto have the met:y lie key harmonize 'with themetal et 'the c sing or the cluster "or other insl'nllalionwi'tli'wliieh it isfilsed.

My intermediate er hill and valley meniber 201s preferably termed etvvporcelain .und

`rocks upon the pivot ll) received in the re' cesses 1S, 1H in -lhei'esiiective insulating My driving meifnber 17 is pi'eferal'ily i.@formed ol; wire and bent to 'form thecui'ns ,ledge 29.

Figs. Il and 10.

Upon the rotation of the key or driving shaft 17 in either direction,the cam 15 or 16, as the ease may be, will coperate withthe insulatingintermediate or hill and-valley member 20 and cause the resilient drivenmember 11 or 12, Whichever one is used, to store up energy by causingthe two free ends of the resilient driven memberto. ap; preach eachother. When suflicient lenergy has been stored up in the spring ordriven member 11or l2, the kicker or accelerator 30, at 'a certainpredetermined position on the rocking of the intermediate meinberQ'O,
